Segmentation fault in alignment

[wbvguo]

Dear BitmapperBS developer,

I installed the latest bitmapperBS (v1.0.2.3) by git clone the source code and make (GCC version 9.4.0), the installation works well, I can see bitmapperBS and psascan in the folder. The genome indexing part is also good, with the following message:

.........
The length of Genome is 3217346917:

But the alignment runs into trouble (Segmentation fault (core dumped)):

I also tried the install and run it with conda, the installation is good, but also run into the following error.

$bitmapperBS --help
Illegal instruction (core dumped)

I tested all above on a server running on ubuntu system (20.04) that supports sse4_2. I also tested on another cluster node running on centos 7, which supports AVX2, it has the same alignment issue.

May I ask if you have any idea to make it work?

Thanks!
